How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...

Comparison of that ancient DNA with modern human DNA showed that the two species had interbred and that people today still carry the genetic fingerprint of that intermixing. Since then ...

For decades, we’ve believed the bright redness of sunburn — along with its irritating sting and peeling skin — was the result of ultraviolet (UV) radiation wreaking havoc on DNA. But now, a new study ...

Complementary base pairing of the carbonless nucleotide analogues and a carbonless DNA dimer proved to be geometrically comparable to conventional DNA molecules, with minor changes to the molecular ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means ...

A 2015 report published by a private genomics testing company found that 2% of 345 hot dogs tested contained traces of human DNA. However, it was unclear whether that report was a peer-reviewed ...
